Gluten-Free Pumpkin Coffee Cake
Pumpkin coffee cake is what the sour cream version becomes in October. Canned pumpkin in the batter, pumpkin pie spice in the filling, and toasted pumpkin seeds across the top.
The pumpkin replaces the sour cream entirely, so the crumb is softer and a shade denser, with the color and the warm spice you expect from the season.
Built on Pamela's Pancake & Baking Mix, which means no baking powder to measure and no xanthan gum to add.
So good, no one will guess it is gluten-free, the way Pamela's has done it since 1988.
Toast the Pumpkin Seeds First
This is the step that makes the recipe, and it takes eight minutes.
Spread all the pumpkin seeds on an ungreased pan and bake at 350 degrees F for 8 to 10 minutes, until they start to turn golden. Do the whole quantity at once, since half goes into the filling and half goes on top.
Untoasted seeds are soft and taste of very little. Toasted, they go nutty and crisp and they hold that texture through the bake.
Watch them. They go from golden to burnt quickly, and burnt pumpkin seeds are bitter enough to carry through the whole cake.
Canned Pumpkin, Not Pie Filling
The recipe calls for one cup of canned pumpkin, and the label matters.
Canned pumpkin is pure pumpkin. Canned pumpkin pie filling is pumpkin with sugar and spices already added, and using it here makes the cake far too sweet and throws off the liquid balance.
Check the front of the can. They sit next to each other on the shelf and the packaging is nearly identical.

If the Center Dips
Pumpkin adds a lot of moisture, which makes this cake slightly more prone to sinking than the sour cream version.
If yours dips in the middle, add a quarter to a half cup more Pancake & Baking Mix next time. That is almost always a measuring difference rather than a problem with the recipe.
Weighing helps more than anything else. We use 140 g per cup, and a scooped cup can run 20 g heavier or lighter depending on how packed the bag is.
Bake it fully. 50 to 60 minutes, and the toothpick needs to come out clean rather than with moist crumbs. A pumpkin batter stays wet longer than a plain one.
